A prolific actor, impressionist and comedian, John Gibb Marshall
took the stage name of Sessions soon after beginning work as a
performer. He graduated with an MA in English Literature from
Bangor University, and began studying for a Phd at McMaster
University in Ontario, Canada but left before completing his
work.

Instead, he took up study at the Royal Academy of Dramatic Art,
better known as RADA, in the late 1970s, where he was a
contemporary of Kenneth Branagh.

Sessions began working on the small venue comedy circuit, where
he eventually played a double bill with French and Saunders. This
work spun out into television, where he featured an improvised
stand up series simply titled 'John Sessions' from 1989.

He continues to flex his comedy muscle in British television
panel shows, including 'Have I Got News for You' and the Stephen
Fry fronted 'QI'.

As an actor, Sessions has appeared in numerous Shakespeare
productions in cinema, including 'Henry V' (1989) directed by his
friend Kenneth Branagh, 'A Midsummer Night's Dream' (1999), and
'The Merchant of Venice' (2004) starring Al Pacino. On television,
his work includes 'Boswell and Johnson's Tour of the Western Isles
(1993), 'Gormanghast' (2000), 'Judge John Deed' (2001 - 2007), and
appeared as Kenny Price in 'Sherlock: The Great Game' (2010). In
2013 John made another Holmes related appearance in an episode of
'Mr Selfridge', featuring as Sir Arthur Conan Doyle. The episode
also featured a sly cameo from Martin Freeman.

He has also played two British Prime Minsters in film - in 'Made
in Dagenham' (2010) he appeared as Harold Wilson, and in 'The Iron
Lady' (2011) as Edward Heath - who was ousted by Wilson at the 1974
General Election.
